Botanical painting in watercolour is the focus of Billy Showell's practical, heavily illustrated art books. Watercolour Flower Portraits breaks flowers into studies of form, colour, layering and detail, while Billy Showell's Botanical Painting in Watercolour develops a broader method for producing precise, luminous botanical subjects.

Watercolour Flower Portraits or Botanical Painting in Watercolour provide the most useful entry points for her core method. Read more Less
